'even-handed' originates from the combination of 'even,' meaning 'level or equal,' and 'handed,' referring to the use of hands in a balanced manner.

'even-handed' evolved from the Old English word 'efen,' meaning 'level or equal,' combined with 'handed,' which has remained consistent in meaning.

Initially, it meant 'using both hands equally,' but over time it evolved into its current meaning of 'fair and impartial.'
